I am not going to defend GM for anything but I think it's fair to say that the engine "cutting out" thing is a very rare problem. I am a frequent visitor of a discussion board with several thousand members who have ZR2 trucks and blazers, and I don't know anyone else who has had this problem before. However, having O2 sensors go out which causes similar problems (but not as serious) is not that uncommon.

In general, GM trucks are really well built and tough in my opinion. However, the quality of parts and the workmanship putting them together is horrible, which leads to lower quality overall. But the main parts, as in engine, transmision, and drive axles, are usually very reliable.

The land cruiser starts at over 50K here ... it is Toyota's most luxurious and expensive offering here in the US.
